crank position flywheel 700

i'm rebuilding a B230FT from a '91 740 and i forgot to mark the position of the flywheel when i removed it from the crank. by matching some discolorations on the crank and flywheel mating surfaces, i think i have it reassembled correctly. but, i would have assumed that the blank spot (in the series of divots around the parimeter of the flywheel) would be lined up with the crank postion sensor when 1 and 4 are at TDC; it is not. the blank spot roughly corresponds to about 90* ATDC (near the starter)--another way of saying it: the blank spot would hit the crank postion sensor around 90* BTDC for 1 and 4. am i off? how can i tell that i have the flywheel on correctly? the haynes manuals were of no help.

thanks in advance,

ryan

      I saw that too, but I think it refers to the old "mono-something"(?) built-in sensor used in a Volvo equipped shop -- not the RPM sensor used with the EZK ignition that came to 240s in '89, which I believe is Ryan's concern.

    Sounds about right, that's where the spot approximately is. Anyway, best way is to fire it up before installing the transmission. If you got it right it'll run right, if you didn't you've got easy access to try alternate positions.
